World standings leader Kody Lostroh won the fourth round of the Professional Bull Riders World Finals on Thursday night, scoring 90.25 points on Mission Accomplished to become one of only three cowboys to cover all four bulls.

"That bull is always good," said Lostroh, who earned $25,000. "Guys get a lot of points when they ride him. He turned back right there into my hand. I got to spur him a little bit, got some extra points and it worked out just like it's supposed to."

JB Mauney, 480.5 points behind Lostroh in second place in the world standings, was second in the fourth round with an 89 on Fire Plug.

"I expect JB to stay on every time he nods his head," Lostroh said. "So, I'm not even watching him, and to be honest with you, I don't care what he does. I'm here to do my job. He's here to do his job, and you guys are here to make a big deal about it."

Defending world standings champion Guilherme Marchi, 1,473.25 points behind Lostroh in third place, has had four unsuccessful rides in the finals. He was bucked off Stinger in 3.1 seconds Thursday.

Mauney leads the event standings with 358 points. Lostroh and Valdiron de Oliveira _ third Thursday after an 88.25 on Copp Hou _ are tied for second at 353.5.

Aaron Roy, Dustin Elliott and Ryan McConnel moved up in the event standings.

Roy was fourth in the round with an 87.5 on Migraine, Elliott finished seventh with an 86 on Derringer, and McConnel was eighth at 85.75 on Bad Action.

McConnel was fifth with 265 points, Roy sixth with 262.25, and Elliott seventh with 261. They have each covered three bulls.
